Inogen One G3 Replacement Column Pair - Oxygen Accessories - Two Removable Metal Columns - 1.63 lbs., 17.8 x 3.66 x 3.62 in.

Easy to replace

I have ordered the columns 3 times to keep my Inogen portable oxygen machine working. It is a lot cheaper to spend your money on replacing the columns then to purchase another unit. I do use the unit more then before, if I leave the house it goes with me. The price is good and the cost for the columns hasn’t increased that much in the 8 years that I have had the unit.

It was so easy to replace and works like charm! Perfect!

They were perfect.

Exactly what I ordered. Easy install.

My Inogen G3 only has 185 hours but is 5+ years old. Inogen suggested I replace the Columns, even though hours are low. My Lungs don't perform well enough at altitudes over 3500 feet. Blue Cross Insurance won't approve an Oxygen Concentrator. So I lucked out and bought mine at an Estate Sale for $25. The Concentrator works perfectly with new Columns and Battery. We are on a trip now with altitudes as high as 6000+ feet. My SPO2 is around 94 - 96 with Concentrator at level 3 and around 4000 to 4700 feet. I had to go level 4 above 5400 feet. I never smoked, am athletic, reasonable weight, yet my SPO2 is below 95 most of the time without the Concentrator, at 200 feet altitude, and at Home. During sleep, 50% of the time, SPO2 is 91 and below. No one knows Why? Thanks Inogen.
